Hi again 78rusty, Unfortunately it is impossible to give an exact date of manufacture of a particular Scott Bonnar machine, as the serial numbers did not run sequentially....and the date was not stamped on the mower anywhere.... cry
However, I can tell you that production of the SB Model 33 had ceased by 1966....so it was a 6 year run. wink
cheers2
